usb: dwc3: ep0: fix status phase delayed status direction
commit 68d3e66 (usb: dwc3: ep0: fix for possible early delayed_status) added handling for early delayed status, but the current code only works because so far delayed status will always be on the IN direction. This patch makes the code more robust by making sure that we can handle all directions properly. Signed-off-by: Felipe Balbi <balbi@ti.com>
